Currently the only AR I own is a RRA. I bought it before I knew what I know now and I am looking to continue running what I call preventive maintenance on it. What I'm getting at is as of now I'm still running the factory BCG in the rifle. I'd like to upgrade to a BCM BCG, can I just drop this in and fire away? Can I use a BCM bolt in the RRA BCG? What things do I need to look for to make sure I don't damage the rifle or myself? I've got my eye set on a complete BCM but as of now I'm just window shopping so the RRA is gonna have to do for now. Thanks
